IPC: A61K47/48
Filed: 1996-10-23
Abstract: Conjugates of GnRH are constructed from GnRH or an analog thereof, a reduced Pseudomonas exotoxin, or a variant thereof, and a unique linking group. The conjugates are administered to male and female animals to sterilize said animals or to reduce tumors that require sex steroids for growth. The instant conjugates are therefore useful as sterilizing agents and anticancer agents.

Title: Corner bumper for use on movable objects
Inventor: TSUI JONES
IPC: E02B3/26
Filed: 1998-09-25
Abstract: A  unique  corner  bumper  for  use  on  movable  objects  and particularly  on  movable  vehicles,  such  as  trucks  and  truck trailers,  to protect a fixed or stationary object,  such as a building or other rigid structure, against the force of an impact by the movable object.  In another embodiment, the corner bumper can be used on a stationary object, such as a boat dock, to prevent damage to impact by a movable object, such as a boat and, in this case, the bumper would be secured to the fixed object, such as the boat dock.   The corner bumper has a pair of elongate sections integrally connected together at common ends and which elongate sections  have  generally  perpendicularly  arranged  interiorly presented surfaces and an upper top wall.  The bumper has tapered exteriorly presented side wall surfaces so that it is generally resistant to being sheared off of the movable object, in the event of an impact with a stationary structure or, for that matter, from a fixed object by contact with movable object which engages the bumper in a shearing position,  as on an end portion thereof.         Moreover, the corner bumper is provided with interiorly formed openings thereby effectively creating ribs between the openings in the structure which are capable of at least partially collapsing or compressing upon impact with a stationary structure.

Title: Seat belt tension prediction system using an accelerometer mounted to the seat frame and a weight sensor
Inventor: STANLEY JAMES GREGORY
IPC: B60N2/90
Filed: 1998-05-12
Abstract: A vehicle seat belt tension prediction system and method comprises an accelerometer (20) having an output signal responsive to vertical acceleration of the vehicle, a seat weight sensor (30) having an output signal responsive to the force exerted by a mass resting on the seat, and a processor means (50) for calculating seat belt tension.

Suitable programming is provided to instruct the processor (50) to calculate the average mass resting on the vehicle seat and predict the force that should be exerted on the seat for a measured level of vertical acceleration assuming zero belt tension. The processor (50) then compares the actual force measured by the seat weight sensor (30) with the predicted force to determine seat belt tension thereby obviating the necessity of complex hardware in physical contact with the seat belt system.

Inventor: GERICKE MICHAEL
IPC: B60K15/04
Filed: 1999-04-13
Abstract: A fuel cap assembly for use with a filler neck of a fuel tank. The cap assembly includes a tubular housing having a shaft. The housing secures the cap assembly to the filler neck of the fuel tank. An exterior cover is mounted to the housing for relative rotation about the housing. The cover has an integral hollow handle. The cap assembly is characterized by a pair of actuating fingers movably mounted within the handle. The fingers engage the shaft of the housing to selectively interlock the cover to the housing.

Inventor: HOERPEL GERHARD
IPC: B01D46/42
Filed: 1998-09-18
Abstract: L'invention concerne un filtre à gaz, son procédé de fabrication et son utilisation. La filtration des gaz, notamment des gaz contaminés avec des matières solides, comme par exemple les gaz d'échappement de voiture, est difficile, les matières solides éliminées par filtration obstruant le filtre avec le temps. Ce filtre à gaz peut s'utiliser sur de plus longues durées car il est régénérable. Le perfectionnement apporté par rapport aux filtres à gaz traditionnels consiste en ce que ce filtre présente un matériau composite pouvant être chauffé de façon simple par application d'une tension sur son support électroconducteur, et en ce que les substances pyrolysables suceptibles de bloquer le filtre peuvent être désintégrées. Ce filtre peut s'utiliser dans tous les cas où des gaz contaminés avec des matières solides pyrolysables doivent être épurés.
